The business model of internet cafes is no longer capable of success

The business model of internet cafes is no longer capable of success in the United States. This is because the availability of internet has skyrocketed over the past several years. Free wifi is offered in most major coffee shops and stores. Additionally, Americans have mobile devices with plans that provide them with internet access. For those without devices, public libraries also provide computers offering internet access, free of charge.

The argument depends on which of the following assumptions?

A. Public libraries are the only source where one can use internet.
B. Internet cafes do not offer any other services, other than internet, that would enable them to be profitable.
C. Major coffee shops are in direct competition with internet cafes.
D. Internet cafes were profitable five years ago.
E. Internet cafes can still be profitable in other countries, just not in the United States.
